About me

I received my Ph.D. degree in ECE(Electrical and Computer Engineering) at the University of Wisconsin Madison in 2021. I was part of Computational Optics Group lead by Professor Andreas Velten. My research interest lies within computational imaging, signal processing, optical engineering and machine learning. I develop computational algorithms and design optical imaging systems that can "see around corners". I enjoy prototyping imaging systems and bringing them into "real-world". My representive works are published in Nature and Nature Communications.
